Difference between rigidity and flexibility of kitchen and bathroom waterproofing

Summarize the waterproof project? Which is better, rigid waterproof or flexible waterproof?

This is a problem that many owners are entangled in. In order to prevent everyone from stepping on the pit, this copy was completely exposed.

1. Rigid waterproofing has the advantages of simple construction, no need to roughen the wall surface, good adhesion with mortar and direct bonding with wall tiles, but it has a very serious disadvantage, that is, poor tensile strength. As long as the house sinks or the temperature difference changes too much, cracks and water seepage may occur in the later period, so it is suitable for the wall.

2. Flexible waterproof, its bright spot is high tensile strength, large elongation, not easy to deform and crack, and its disadvantage is very smooth surface. If you don't do the napping treatment later, the wall tiles will fall off in a large area later.

3. These two kinds of waterproofing have their own advantages and disadvantages. In order to be foolproof, you can do a flexible waterproofing first, and then do a rigid waterproofing from the ground to the wall as a whole after completing the water avoidance test.

In this way, waterproof is double-insured, and the cohesive force of wall tiles is greatly increased, so there is no need to worry about tile falling off. This practice is much better than simply taking a nap.

4. It should be specially reminded that when pasting the bathroom door in the later period, the outside should be brushed again to prevent water from seeping under the tiles and flowing to the door, so that the bathroom door will not rot and the peeling phenomenon will not appear on both sides of the bathroom door.
